How Normal is Our Solar System?
To date, we’ve discovered nearly 2000 confirmed exoplanets, as well as thousands of additional candidates. Amidst this vast sea of solar systems, how special is our own?
Collapsing Enormous Stars
A recent study explores what we would see if supermassive stars in the early universe collapsed directly into black holes.
Bow Shock Leads the Way for a Speeding Hot Jupiter
A bow shock has been detected ahead of transiting exoplanet HD 189733b, providing a potential indicator of the remarkably strong magnetic field of the planet.
What X-Shaped Sources Tell Us About Gravitational Waves
A new study suggests we may be over-predicting the rate of galaxy mergers — and the gravitational wave background — by counting X-shaped radio sources.
What’s Causing the Activity on Comet 67P?
Recent models provide an explanation for the “early activity” unexpectedly emerging from the neck of comet 67P.
Forming Stars From the Cosmic Web
Observations of starbursts in low-metallicity galaxies have provided long-awaited evidence supporting predictions of how stars formed throughout cosmic history.
Water Vapor in an Unexpected Location
A recent study has found that the transitional disk DoAr 44 contains water vapor in its inner regions.
